To all whom it may concern:

Be it known that I, Sansone A. Moss, a citizen of the United States, residing at liynn, county of Essex, State ol' Massachugroove in the projection 12 to hold the govsetts, have invented certain new and useful & ernor in position. Improvements in Governing Mechanism for disposed members 14 at the top 01 the co'l- Oil or Gas Engines, of which the following is :umn are mounted the arms 15 and 16 which a specification. carry at their lower ends the balls or weights The present invention relates to a govern-' 17 and 18. Pins 1!! and 20 mounted in the ing mechanism foroil or gas engines which members 14 furnish bearings for the govkeeps the engine speed constant by rcgulaternor armsl Centrally mounted to slide ing' the quantity of the charge of air .and 1 within the column 1.1. and the projection 12 combustible admitted to the cylinder. As is a shaft 21 having a pin 22 at its upper end, the quantity of the charge is varied the vewith which the ends of the governor arms locity with which it travels to the cylinder have a sliding connection. The lower porfrom suitable sources of supply tends to tion of shal't21 is reduced at 23 to receive the var This variation in velocity will cause forked end. of a lever 24 pivotally mounted irregular variations in the supply of combusupon the casing. The other end'ol the lever tible and consequent irregular variations in has a slotted connection with the upper end 01'' a valve spindle to be described.

For the purpose of controlling the admission of air and fuel or combustible to the'eylinder, a cylindrical valve 25, Fig; 3, is mounted in a eorrespondingly-sha1)ed portion of the casing S which forms a seat for the valve. Air enters through the upper part of this portion of the casing while fuel from any suitable source of supply is admitted by pipe 26 at the bottom; Two sets of ports are )IU- vid ed, one for air and the other for combustible or fuel. The cylindrical, wall of the easing has a series of ports 27-and the valve .25 has a corresponding series of ports 28 through which the air may pass. The valve also has a series of ports 29 through which passes to other ports 30 contained in a series of rings 31 surrounding the lower portion of the valve and held in place by a dising from the top of the casing 8; The screw 13, which secures the pulley to the column, extends through the column and engages a The object of my invention is to overcome the irregularities referred to and obtain a proper ratio of air to combustible in the charge under all load conditions. B y my invention the supply of combustible can be regulated independently for several different positions of the-governor mechanism but it is obvious that the desired ratio might be obtained by regulating'the air su )ply instead of the su ply of combustible if desired.

In the accom anying drawings illustrating one of the embodiments of my invention, Figure 1 is a side View of an engine with my invention applied thereto; Fig. 2 is a section on line 2-2 of Fig. 3; Fig. 3 is a vertical section through the governor and the valve controlled by it; Fig. 4 is a section on the line 44 of Fig. 3; Fig. 5 is a section on line 55 of Fig. 4; and Fig. 6 is a sectional view of a modification.

For the purpose of illustration, the invention is shown as attached to a horizontal engine, but it is to be understood that it may beused with a vertical or other type of engine if desired. The engine has a bed plate 1 from which rise supports 2 and 3'for the cylinder 4 and the main shaft 5 respectively. The shaft 5 carries a fly wheel 6 and a grooved pulley 7. A governor or speed-responsive device of any suit-able construction is mounted on a casing 8 which is bolted to the cylinder, and is driven by a belt 9 which.

asses round the pulleys 7 and 10. The M1- ey 10 is fixed to ahollow column 11 w iichrotates on a cylindrical projection 12 extendfive in number but this number may be varied to suit the size of the engine and'th'e desired range of adjustment of fuel to air in the entering charge. The ports 30 are formed between segments of the ringBl and these segments are joined by V-shaped ribs 32 which offer but little resistance to the flow of gas or .fuel. Both sets of ports 27, and 30 open into a passage 33 which leads from the valve to the engine cylinder. Upon a portion of the periphery of each ring 31 is a series of teeth34, Fig. 4, which engage a worm 35 upon a shaft 36 mounted in the Wall of the casing and having ahead 37 which is so s'hapedthat it may be engaged by a screw driver or wrench to turn the worm and there- Bctwecn two oppositelytance )iece 54. These rin s as shown are by rotate a ring 31 to vary the effective area of the ports 29 and 30.

"he valve 25 has a central hub 38 in the upper en'd of which is mounted a stud or s aindle 39 having a pin 40 which engages the slots 41 in the forked end of the lever 24. The pin 40 is held in place by means of a setsercw. The upper end of the spindle 39 is idcd in a bearing formed in a spider 42 which is bolted to the casing. A horizontal partition 43, extending across the middle portion of the valve separates the air from the gas and the valve is further strengthened by a series of radial ribs 44 at its lower end.

In the modification shown in Fig. 6, a flat "slide valve 45 is used in place of the cylindrical valve 25, shown in ig. 3. The valve is held to its seat by springs and has a connection 52 to the governor. A series of manually-operated cocks 46 is used to control the effective area of the ports 47 through which gas or fuel is su plied to the chamber 48. A passage 53 lea s from the chamber to the engine 0 linder. Air enters through the ports 49 an 50in the casing and valve respectively.

In Figs. 3 and 6, the valves and the governor are in their lowest position with the ports all open. This is the position for maximum or heavy load. When runnin under a light load, the valve 25 or 45 will e raised toward its upper limit of movement by the governor. Assumin that the load is such that the valve has 'een moved upward to cover all except the u per one of the rings 31 or ports 47, then the rst or upper ring 31 or valve 46 may be adjusted tosecure the proper opening for combustible under these conditions. When the load has increased so that the next or secondring is uncovered, the effective area of the ports may be adjusted to secure the proper opening under the new conditions by turning valve without disturbing the adjustment of the first ring'31 or valve 46, and-so on with the whole series of rings or valves. In this manner the ratio of combustible to air may be varied to secure any desirablemixture.

In accordance with the provisions of the patent statutes, I have described the principle of operation of my invention, together with the apparatus'which I now consider to represent the best embodiment thereof; but I desire to have it understood that the ap paratus shown is only illustrative, and that the invention can be carried out by other means.
